Abstract

Solid-state reactive diffusion between Ni and Al was investigated during annealing at 650°C by employing multi-laminated Ni-(TiB₂/Al) composite sheets. In multi-laminated Ni-(TiB₂/Al) composite sheets annealed up to 5min NiAl₃ was the only phase observed in the diffusion zone, and Ni₂Al₃ appeared after longer annealing time. Most grains of Ni₂Al₃ showed equiaxed morphology rather than columnar microstructures like NiAl₃, due to the low concentration gradients of Al and Ni at the Ni/NiAl₃ interface. The preferential formation of this intermetallic compound NiAl₃ in multi-laminated Ni-(TiB₂/Al) composite sheets was predicted using an effective heat of formation model. The present work indicated that both Ni and Al interdiffused, and the formation of NiAl₃ was a reaction-diffusion process.
